No-Bake Key Lime Pie

No-Bake Key Lime Pie

Ingredients

  • 1 ½ cups graham cracker crumbs (about 10-12 full sheets)
  • ⅓ cup granulated sugar
  • 6 tablespoons unsalted butter, melted
  • 4 large egg yolks
  • 1 (14-ounce) can sweetened condensed milk
  • ⅔ cup freshly squeezed key lime juice (about 20-25 key limes, or Nellie & Joe’s bottled juice)
  • 1 tablespoon grated key lime zest (optional, for extra flavor)
  • 1 cup heavy whipping cream
  • 2 tablespoons powdered sugar
  • Thin lime slices or zest, for garnish

Step-by-Step Instructions


1. Begin by making the crust. In a medium bowl, combine the graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until the mixture resembles wet sand and holds together when pinched.


2. Press the crumb mixture firmly and evenly into the bottom and up the sides of a 9-inch pie plate. Use the bottom of a flat glass or measuring cup to help create a compact, even layer. Chill in the refrigerator for at least 30 minutes to set.


3. For the filling, whisk the egg yolks in a large bowl for about 2 minutes until they become slightly thickened and pale.


4. Whisk in the sweetened condensed milk until the mixture is completely smooth and well combined.
5. Gradually whisk in the key lime juice. The mixture will thicken noticeably as you mix. Stir in the lime zest, if using.


6. Pour the filling into the chilled crust and spread it into an even layer. Tap the pan gently on the counter to remove any air bubbles.


7. Cover the pie loosely with plastic wrap and refrigerate for at least 6 hours, or preferably overnight, until completely set.


8. Before serving, make the whipped cream. Using a hand mixer or stand mixer, beat the heavy cream and powdered sugar on medium-high speed until stiff peaks form.


9. Spread or pipe the whipped cream over the chilled pie. Garnish with thin lime slices or extra zest. This easy key lime pie recipe is a no-bake wonder, making it the perfect quick key lime pie recipe for warm days when you don’t want to turn on the oven.

Tips & Variations

No-Bake Key Lime Pie
  • Crust Swap: Use a pre-made graham cracker crust for an even faster assembly. For a twist, try a vanilla wafer or shortbread cookie crust.
  • Citrus Swap: In a pinch, regular Persian lime juice will work, though the flavor will be slightly different. For the best authentic taste, use bottled Key West key lime juice.
  • Lighter Option: Substitute the whipped cream topping with a light layer of sweetened Greek yogurt or meringue (though meringue requires baking).

Serving & Storage


Serve the pie chilled, straight from the refrigerator. Use a sharp knife dipped in hot water for clean slices. Store any leftovers covered tightly with plastic wrap or in an airtight container in the fridge for up to 4 days. The pie does not freeze well due to the creamy filling, but the crust can be made and frozen ahead of time.

Nutritional Benefits

Key limes are a good source of vitamin C and antioxidants. While this is a dessert, the protein and calcium from the sweetened condensed milk and egg yolks offer some nutritional value. Enjoy it as an occasional, balanced treat.

Common Mistakes to Avoid

  • Over-mixing the Filling: Whisk just until combined after adding the lime juice. Over-mixing can incorporate too much air.
  • Skimping on Chill Time: The pie must chill for the full 6+ hours to set properly. A runny pie is almost always due to insufficient chilling.
  • Using Bottled “Lime Juice”: Avoid generic bottled lime juice (the kind used for cocktails) as it contains preservatives and has an off-flavor. Only use 100% key lime juice.
  • A Soggy Crust: Ensure your butter is fully incorporated with the crumbs and pack the crust firmly. A loose crust will crumble when sliced.

FAQs

Can I use regular limes instead of key limes?
Yes, you can. The pie will still be delicious, but the flavor profile will be different. Key limes are more aromatic and tart, while regular Persian limes are slightly more bitter. You’ll need about 4-5 regular limes to yield ⅔ cup of juice.

Why is my key lime pie filling not setting?
The most common reason is not chilling it long enough. The pie needs a minimum of 6 hours in the refrigerator for the filling to fully set through chemical reaction (the acid in the juice “cooks” the egg yolks and thickens the dairy). Ensure you are also using full-fat sweetened condensed milk.

How can I tell if my whipped cream has reached “stiff peaks”?
When you lift the beaters out of the cream, the peak that forms should stand upright straight away and not curl over at the tip. The cream will also look thick and spreadable, not soupy or liquidy.

Is it safe to eat a no-bake pie with raw egg yolks?
The acid in the key lime juice effectively “cooks” the egg yolks through a process called denaturation, similar to ceviche. However, if you are pregnant, immunocompromised, or concerned, you can use pasteurized egg yolks or look for a recipe that gently heats the filling on the stove.

Can I make this pie ahead of time?
Absolutely! In fact, it’s better when made ahead. You can prepare the entire pie 1-2 days in advance. Wait to add the whipped cream topping until just before serving to keep it fresh and fluffy.
